    HEVC Video Extensions

    HEVC Video Extensions

    Play HEVC (H.265) encoded videos on Windows

    HEVC Video Extensions from Device Manufacturer is the official application for playing the HEVC (H.265) codec on Windows 10 and Windows 11. Microsoft offers two identical applications for playing this codec natively by hardware. The only difference between them is that one costs money and the other is free. The free one is included on new devices sold by big brands, like laptops that come with Windows pre-installed. These manufacturers don't have to pay to include the codec. Luckily, you can download the codec for free and install it on your own computer. That's what this file offers. After installing it, you can play videos and movies recorded with the HEVC (H.265) codec. Most 4K movies are recorded in this format, so with this application, you'll be able to play them using the native Windows application called Movies and TV.

    AV1 AVIF

    AV1 AVIF

    AV1 Image File Format Specification - ISO-BMFF/HEIF derivative

    AV1 AVIF is the official specification and reference design for the AV1 Image File Format (AVIF), defining how AV1-encoded bitstreams are packaged into the HEIF container format (based on ISOBMFF) to produce AVIF files. The project outlines the syntax and semantics required for AVIF compliance, including support for multiple image profiles, color depths, chroma subsampling modes, HDR/WCG, alpha channels, animation/image sequences, and various color-space/bit-depth combinations — making AVIF a versatile, modern image format suitable for both simple photos and advanced imagery needing high fidelity. The specification ensures interoperability across encoders and decoders, providing guidelines so that images created by any compliant AVIF encoder can be reliably decoded by compliant decoders. As adoption grows, AV1 AVIF plays a crucial role in promoting a royalty-free, open, high-efficiency image standard that competes with older formats such as JPEG and newer proprietary ones.
